BUS'JLESS BUCKLE.

Application filed July 15 To all whom it may concern Be it knownthatMICHAEL HAWIE, citizen of'the United States, and resident of Bridgeport,in the county of Fairlield and State of Connecticut, has inventedcertain new and useful Improvements in Rustlessj Buckles, of which thefollowing is a specification. o The present invention relates toimprovements in buckles, and more particularly to the type ofbucklesknown as rustless back buckles.

An object of the invention is to provide a buckle of this character,which may be s iniply'and economically constructed of two pieces ofsheet metal, stamped to shape, and in which a comparative saving of boththe metal going into the buckle, and the web secured to and co-operatingtherewith, may vbe effected. A further object is to allow the securefastening of.the web, without stitching, or the use of other fasteningmeans, other than that incorporated in the two parts of the buckle.

Still furtherlobjects consist in effectually securing, the web to thebuckle, so that it will withstand excessive strains, and .in'

which the web will not readily become worn or chafed.

With the above and other objects in view, an embodiment of the inventionis shown in the accompanying drawings, and this embodiment will behereinafter more fully described with reference thereto, and theinvention will be finally pointed out in'the claims.

In the drawings:

Fig. 1 is a perspective view of a buckle, embodying the invention,showing the clamping lever opened, and the two parts assembled andbefore attachment to the web;

Fig. 2 is a similar view, showing the web attached and unfolded;

Fig. 3 is another similar view, the web folded down upon itself;

Fig. 4 is a vertical sectional view, and showing the web looped througha cast-off, and carried beneath the closed clamping lever; and

Fig. 5 is a perspective view, showing the inner side of the buckle, andwith the web attached.

Similar reference characters indicate cor responding parts throughoutthe several figures of the drawings.

Referring to the drawings, the buckle showing 1922. Serial NQ.-75,3l,4.

comprises twostamped sheet metal parts, e. a body or frame member and--a clamping" lever member, th latter consisting of an operatlng arm 10,and a clamping arm 11, having a series'o'f teeth 12 along itsedge. The

clamping arm is arranged at an approxie mate acute 'angleto theoperating arm, and l is PIQVlClGQl with pintles 13 and-1 1, extend ingifroi'n' opposite ends of the lever, and situated substantially contiguousto the junc tion between the operating and clamping arms. v,

The frame15 is in. the form of a bar havingparallelnpper and lower edges16 and 17 and is provided at its ends with cars 18 and19, bent at rightangles and perforated at 20 and-21 to receive and pivotally supportthepin-tles 13 and ltof the clamping lever. i

A series of spaced V-shaped teeth 22, hav. ing their points directedtoward theupper edge 16-, and forming corresponding shaped openings 23in the bar'arej struck from frame, and are bent outwardly and upwardly,the points being spaced away from the surface f he bar, beforeattachmentofthe web, as clearly. shown in Fig. 1.

openings 23 are in line with the teeth 12 of the clamping arm, for apurpose which will be presently more-fullypoint'e'd out.

e ri 1 p i o the clamping e ee are arranged above the teeth 22 andopenin s 23, and the teeth 12 are given a circu ar movement toward theopenings 23 with each operation of the lever.

The web 24: is engaged with the buckle by inserting its end 25 beneaththe teeth 22,

which are thereupon swedged, in a suitable manner, inwardly at their.points toward the openings 28, to securely grip the end of the web,which is exposed at the inner sidev of the frame, at its portionsengaged in the openings 23. The web'is then folded downwardly, sothatthe points of the teeth 22 are directed into the bight of the fold, tothere by more securely grip the web, under ex cessive strains; It isthen passed through the cast-off 26, and the upper reach-2'2 is insertedthrough the buckle, between the frame and the clamping lever, the latterbeing,

then closed, so that its toothed edge 12 en gages the web, and pressesit firmly against the inner face of the frame; the portions directlyengaged by the points of the teeth 12,

being tightly and frictionally engaged with the portions of the end ofthe web exposed grip the same proportionately to such strains.

I have illustrated and described a pre ferred and satisfactoryembodiment of the invention, but it is obvious that changes may be madetherein, within the spirit and scope thereof, as defined in the appendedclaims.

I claim:

1. A buckle comprising a sheet metal frame member and a lever member,said frame member including a back having forwardly projecting ears anda series of spaced apart inverted V-shaped cuts forming teeth, all ofsaid teeth being struck outwardly from the back in a direction. opposedto the direction of said ears, whereby the inner surface of said backbetween said ears is free of projections. the pointsofsaid teethextending substantially in the same direction upwardly as the apices ofthe cuts and being spaced from the outer surface of the back to permitthe insertion of a Web having its edge inserted downwardly between theteeth and the outer surface of the back and abutted by the base of theteeth, the end portion of the web being grippingly engaged by said.teeth, and having portions exposed through the openings formed by theteeth at the inner side of the back, the

the web adapted to be folded downwardly upon the teeth to conceal them,the points thereof engaging the bight of the fold to increasingly gripthe web upon downward pull thereon, the lever member being pivoted inthe ears of the frame member and including an operating arm and aclamping arm arranged at an angle thereto and having a gripping edgeadapted in the operation of the lever to engage a reach of the webinserted between the frame and lever.

2. A buckle comprising a sheet metal frame-member and lever-member, saidframe member including a back having forwardly projected ears and aseries of spaced apart teeth struck up from the back intermediate itsupper and lower edges, extending rearwardly, and forming a series ofopenings in the back, said teeth adapted to grippingly engage the end ofa web inserted beneath said teeth at the outer side of the framemember,portions of the web being exposed through said openings at the innerside of the frame, the lever-member being pivoted in the ears of theframe-member and including an operating arm and a clamping arm arrangedat an angle thereto and having a series of teeth arranged in opposedrelation to said series of openings in the back and adapted in theoperation of the lever to engage a reach of the web, inserted betweenthe frame and lever, with the portions of the a web exposed through saidopenings.
